I would for now hand feed them both treats, and feed them their meals in their bowls. I would also keep BOTH of them in the bathroom together, with maybe one toy or two that makes a rattle noise, like a small ball. Check in on them as frequently as you can and approach them slowly with one of your hands out for them to smell.
Blink every once in awhile while you are talking to them and making eye contact. That's what they do to us humans to let us know that they are starting to trust us. It will make them feel better rather than a constant gaze or a stare.
Then, if you had the time, you could sit in the room with them while they ate their dinner and talk to them both.
They'll come around. You are doing the absolutely right thing in putting them in a small space when introducing them to their new home. So many people don't do that and they cats get really freaked out and go hide under the bed or in a closet. We recommend about 2 weeks of this, unless they come around sooner.
